Description
Destination IP
Address
Specifies the IP address of the destination computer or an entire destination
network. It can also be specified as all zeros to indicate that this route should
be used for all destinations for which no other route is defined (this is the
route that creates the default gateway). Note that destination IP must be a
network ID. The default route uses a destination IP of 0.0.0.0. Refer to
Appendix 13 for an explanation of network ID.
Destination Netmask
Indicates which parts of the destination address refer to the network and
which parts refer to a computer on the network. Refer to Appendix 13, for an
explanation of network masks. The default route uses a netmask of 0.0.0.0.
